S. Somasegar just announced the WinFX name change. It's now the .NET Framework 3.0. This is a name change for the technology, which still has all of the great parts: Windows Presentation Foundation, Windows Communciation Foundation, Windows CardSpace, and Windows Workflow Foundation. I think that this makes it clear that WinFX is not a separate entity from .NET, the two have always been tied very closely together, and the naming now reflects this.
We'll be rolling out a new version of www.windowsworkflow.net shortly, watch this space for more details!
